Posted by Bill West on Tue Sep 15 02:32:41 2009, in response to Re: Fourth Rails and Safety, posted by Wado MP73 on Mon Sep 14 11:37:33 2009. Vancouver's Skytrain uses 4th rail, mounted one above the other outside the running rails.When I saw it the safety signs on the platform alleged that there was an intrusion detection system for the track area. Don't know if this was a bluff or for real, nor what it did if it went off. Bill |
